{"id":"CVE-2026-43151","summary":"Revert \"media: iris: Add sanity check for stop streaming\"","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nRevert \"media: iris: Add sanity check for stop streaming\"\n\nThis reverts commit ad699fa78b59241c9d71a8cafb51525f3dab04d4.\n\nRevert the check that skipped stop_streaming when the instance was in\nIRIS_INST_ERROR, as it caused multiple regressions:\n\n1. Buffers were not returned to vb2 when the instance was already in\n   error state, triggering warnings in the vb2 core because buffer\n   completion was skipped.\n\n2. If a session failed early (e.g. unsupported configuration), the\n   instance transitioned to IRIS_INST_ERROR. When userspace attempted\n   to stop streaming for cleanup, stop_streaming was skipped due to the\n   added check, preventing proper teardown and leaving the firmware\n   in an inconsistent state.","modified":"2026-07-08T08:13:28.415815161Z","published":"2026-05-06T11:27:33.084Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/43xxx/CVE-2026-43151.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/370e19042fb8ac68109f8bdb0fdd8118baf39318"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a58b9d1c1cf81c0b29f1983c63c3e0c0caa68398"},{"type":"WEB","url":"https://git.kernel.org/stable/c/bd4f8fa216182f33c06d4c1e162975a0c42fb14e"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/43xxx/CVE-2026-43151.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-43151"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"f8b136296722e258ec43237a35f72c92a6d4501a"},{"fixed":"bd4f8fa216182f33c06d4c1e162975a0c42fb14e"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"ad699fa78b59241c9d71a8cafb51525f3dab04d4"},{"fixed":"a58b9d1c1cf81c0b29f1983c63c3e0c0caa68398"},{"fixed":"370e19042fb8ac68109f8bdb0fdd8118baf39318"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"6.18.3"},{"fixed":"6.18.16"}]}],"versions":["v6.18.15","v6.18.14","v6.18.13","v6.18.12","v6.18.11","v6.18.10","v6.18.9","v6.18.8","v6.18.7","v6.18.6","v6.18.5","v6.18.4","v6.18.3"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-43151.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.18.16"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"6.19.6"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-43151.json"}}],"schema_version":"1.7.5"}
